` INHALER Filed sept. 27, 1957 I A TTORNEYS.

ratented Mar. 22, 1938 UNITED STATES PATENT OFFICE Application September 1 Claim.

This invention relates to an inhaler designed primarily for use in the treatment of pulmonary diseases, one of the objects being to provide a simple and efiicient device of this character in which the fumes of as many as three different medicines or chemical mixtures can be inhaled in any predetermined proportions to meet the reit being understood that changes may be made in' the construction and arrangement of parts Without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention. has been shown.

In said drawing. V Figure 1 is an elevation of the inhaler. Figure 2 is an enlarged section through the container portion thereof.

Figure 3 is a plan view, the inhaling tube being broken away. j

Referring to the figures by characters of reference l designates a container preferably of glass and of any suitable proportions, the same being provided with a lid or cover 2 formed preferably of soft rubber having a fiange 3 for embracing and firmly gripping the outer surface of the container. This cap is formed with spaced openings yy, 4 and 5 adapted to receive supplementalcontainers' and I respectively formed preferably of glass and each having an annular fiange 8 at its upper end for overlying the adjacent portions of the cap or closure so as to prevent the same from slipping down too far into the cap. Each of these supplemental containers is open at the top.

Tubes 9 and iii formed preferably of glass are extended through holes I l provided therefo-r in w the cap 2, each of these tubes having a long arm extending downwardly into the main container I' 27, 1937, Serial No. 165,961

connected to it. This suction tube can be formed with separate extensions |6 terminating in nozzles l'l fo-r insertion into the nostrils of the patient or a single suction tube can be used for insertion into the mouth of the patient.

In using the inhaler one medicament is placed in the main container as indicated at A. Another medicament is placed in supplemental container 6 as indicated at B while a third medicament is placed in supplemental container 1, as indicated at C. When. the patient draws air through the tube 15, While inhaling, fresh air is pulled into the crooks |2 and |3 between the fiared ends thereof and the open ends of the supplemental containers 6 and 1. The air thus fiowing into the crooks picks up fumes generated in the supplemental container, carries them downwardly through the tubes 9 and IO from which they escape into the medicament A and rise into the upper portion of main container I from which they are withdrawn by suction on the tube 15. Thus it will be noted that fumes from the three medicaments are fairly mixed before they enter the nose or mouth of the patient and by sliding the tubes 9 and H] longitudinally the amount of air drawn into each crookV in proportion to'the fumes collected thereby from containersi and 'l can be easily regulated. For example by thrusting the open ends of the crooks well down into the containers 6 and 'I the proportion of fumes to air will be much greater than where the open ends of the crooks are adjusted upwardly away from the containers 6 and 1. O'bviously, as the crooks are separately adjustable the proportions of the fumes from the respective receptacles 6 and 'l can be varied. Furthermore as the tubes 9 are rotatably as well as slidably mounted in the cap 2, it is a simple matter to swing the crooks away from positions over the supplemental containers 6 and 1 so as to permit medicaments to be placed readily in the containers.

What is claimed is:

An inhaler including a main container having a suction tube extending therefrom, a cap sealing the container and supporting the tube, supplemental containers Within and supported by the cap, tubes slidably and rotatably mounted within the cap and extending into the main container adjacent to the bottom thereof, and crooks at the upper ends of said tubes and adjustable relative to the respective supplemental containers for receiving fumes therefrom and for receiving fresh air sucked into the crooks, the inlet end of the crooks being flared.
